Messed up on taxes

Hello,

 I messed up on my taxes I marked something wrong which is now affecting my mom for filing saying she owes a large amount. I already received my tax refund but my mom hasn’t yet filed. What happens if I can’t amend my taxes till 03/25/21 and the filing period ends April 15th. She won’t be able to file on time if the IRS takes a while to process the Amend form correct?
